Sobre survival analysis
Hola Estoy tratando de correr un survival analysis usando un Cox regression model. Tengo una duda respecto a la organizacion del script. Tengo una variable que es -tamano del individuo- y quiero ver si hay diferencia en sobrevivencia respecto a tamano. Como diseno de campo los tamanos fueron ubicados de forma aleatoria en bloques al azar. Cuado planteo el script tengo algo como:

MuMIn - assessing variable importance following model averaging, z-stats/p-values or CI?
Dear R users, Recent changes to the MuMIn package now means that the model averaging command (model.avg) no longer returns confidence intervals, but instead returns zvalues and corresponding pvalues for fixed effects included in models. Previously I have used this package for model selection/averaging following Greuber et al (2011) where it suggests that one should use confidence intervals from

Significance of interaction depends on factor reference level - lmer/AIC model averaging
Dear R users, I am using lmer combined with AIC model selection and averaging (in the MuMIn package) to try and assess how isotope values (which indicate diet) vary within a population of animals. I have multiple measures from individuals (variable 'Tattoo') and multiple individuals within social groups within 4 locations (A, B, C ,D) crucially I am interested if there are

Hi, I am an R newbie and one thing I am having trouble with binding variables that I have created within one data frame into a new data frame when using na.omit(). To illustrate this problem I will give the example I am working on and the approah I have been using:- data.frame1<-filepath.... attach(data.frame1) #create a new variable using a function new.variable<-rep(1,length(weight3))

MCMCglmm priors including phylogeny
Hi all, I'm hoping I might be able to get some help with some issues specifying priors for MCMCglmm. I'm trying to fit a gaussian glmm using MCMCglmm to a data set with two (correlated) response variables. The response variables are both logit-transformed proportions (there are a few reasons why I've chosen these with gaussian error over binomal glmm, which I won't go into).

Pregunta sobre RMarkdown
Hola Carlos, creo que no resuelve el problema, de hecho otra de las cosas que no he conseguido aún es generar sencillamente el PDF (con los html para generarlos 1 a 1 sin pb). Siempre suelo obtener el error. Esto me aparece al ejecutar myReport$export(): You may install Pandoc easily with "install.pandoc()" from the "installr" package.Error in Pandoc.convert(fp, format =

Residuals from GLMMs in the lme4 package
Hello there This is the first time I have used r-help message board so I hope I have got the right address. I am trying to check the residuals of a GLMM model(run using the package lme4). I have been able to check the residiuals of REMLs in lme4 using the following: m1<-lmer(vTotal~Week+fCollar+ (1|fCat), collars) res<-resid(m1) plot(res) qqnorm(res) library(MASS) par(mfrow=c(2,3))

Pregunta sobre RMarkdown
Hola, ¿qué tal? Lo que puedes hacer es que tu fichero Rmd lea el parámetro de un fichero externo. Entonces, creas un script que: 1) Actualice el valor del índice en ese fichero externo. 2) Compile el Rmd y le dé el nombre que te interesa. 3) Vuelva a (1). Salud, Carlos J.

simplifying a lmer model
I have been using lmer in lme4() to analyse the effect of dropping a term from the model as below anova.name<-anova(m1,m2) Where m1 is an original model and m2 has one term removed. I can then create my own type III tables for each variable in the model. However with many variables this becomes exceedingly time consuming! anova.lme in nlme() and Anova() in car dont seem to work for lme

Missing interaction effect in binomial GLMM with lmer
Dear all, I was wondering if anyone could help solve a problem of a missing interaction effect!! I carried out a 2 x 2 factorial experiment to see if eggs from 2 different locations (Origin = 1 or 2) had different hatching success under 2 different incubation schedules (Treat = 1 or 2). Six eggs were taken from 10 females (random = Female) at each location and split between the treatments,

Plot confidence intervals
   Hello, list:    I'm not sure about where to send this question. I have several repeatability calculations, together with their 95% confidence intervals, and I would like to plot them, in a way similar to error bars. I was wondering if there is any specific function to do this, or any method I can apply in R, as I haven't found anything like that in the R book.    Thank you very much
